No problem. I should point out that it’s a very US-centric version of history. I’m sure it leaves out a ton of international context. If anyone else knows of a book that includes more international context I’d love to read it myself.

You should read Hackers: Heroes of the Computer Revolution by Steven Levy.

It shouldn’t scare you that it’s possible to identify people on a dating app where users typically share personal information, and on one that is presumably pretty reliant on location data. That you can be identified with the information you provide these services should be the absolute bare minimum you expect to be possible.

You can likely be positively identified by a website you visit without entering a single bit of personal information on that site, based purely on data which that site is able to acquire from 3rd parties and the IP+browser you are connecting with. Now that should scare you.
